<p>Sets a minimum ms delay for each iteration (default is 0). </p>
<p>This function should be called to establish a minimum delay for each iteration (that is, it should be used to limit the speed at which the block iterates). Of course, if the real processing iteration time is longer than the delay set with this function, it will not have any visible effect.</p>
<p>Warning: due to underlying operating system time management imprecissions, low values (typically under 40 ms) of this parameter can result in longer delays than expected. </p>

<p>Adds a trigger to the block. </p>
<p>Triggers are just named actions that can be called upon a <a class="el" href="classQVProcessingBlock.html" title="Base class for Block threads.">QVProcessingBlock</a> to change it's state, initialize itself, or whatever action the programmer considers convenient, in a completely asynchronous manner. When added to a block, they will depict a button in the corresponding property widget in the interface, that will do a call to <a class="el" href="classQVProcessingBlock.html#adb13844954356bd9ed1bfbe97d731095">processTrigger()</a> function when pressed.</p>
<p>This method is provided just for convenience. The same effect could be achieved just by adding a new slot when subclassing <a class="el" href="classQVProcessingBlock.html" title="Base class for Block threads.">QVProcessingBlock</a>, and connecting it to a button clicked signal. But using this generic function avoids the programmer to have to declare the new block class as a Q_OBJECT, if he just needs the trigger functionality, and does not want to declare any other signals or slots in his new block class. </p>
